Description

Technical Field

[0001] This utility model relates to papermaking equipment, specifically a paper-leading rope system for paper production. Background Technology

[0002] The guide rope system, also called the paper guide rope system or traction rope system, is a device on a paper machine used to safely and efficiently guide new paper webs (wet paper) through the drying section. Its core function is to replace the fragile wet paper sheet in bearing the mechanical tension during the initial paper feeding after a paper breakage or when feeding paper for the first time upon restarting the machine, preventing paper web breakage and ensuring production continuity and efficiency.

[0003] In existing paper guide wheel systems, the guide wheels are guide wheels mounted on both sides of the drying section, primarily providing a track for the paper guide rope. The guide wheels are movably mounted on a rotating shaft via bearings, and components are installed on the rotating shaft to limit the bearings and guide wheels. However, if the guide wheel or bearing malfunctions during operation and requires repair, the entire machine must be stopped. After stopping, the components used to limit the guide wheel and bearing must be removed from the rotating shaft, and then the entire guide wheel and bearing must be removed from the rotating shaft for repair. This requires stopping the entire machine, making repairs cumbersome and impacting production efficiency. Therefore, a paper guide rope system for paper production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a paper-leading rope system for paper production in order to solve the above problems.

Detailed Implementation

[0012] The paper-feeding rope system for paper production described in this utility model will now be further described with reference to the accompanying drawings.

[0013] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

The rope-feeding wheel 4 is provided with a plurality of mounting shafts 51 for mounting the small traction wheels 5, and a bearing 52 is installed between the mounting shafts 51 and the small traction wheels 5. By installing several small traction wheels 5 protruding from the outer ring of the guide rope wheel 4 on one side, the small traction wheels 5 replace the guide rope wheel 4 to provide the running trajectory for the paper guide rope. By installing the small traction wheels 5 on the outside of the guide rope wheel 4, when the small traction wheels 5 or the bearing 52 between the small traction wheels 5 and the mounting shaft 51 fails and needs maintenance, the small traction wheels 5 can be directly removed from the mounting shaft 51 for maintenance without having to stop the entire equipment and remove the guide rope wheel 4 for maintenance. This facilitates maintenance operations without stopping the machine.

During the rotation, the drive wheel 73 drives the guide rope to move through the friction between it and the guide rope. The transmission wheel 72 is used to guide the guide rope.

[0018] When this utility model is in use: when the small traction wheel 5 and bearing 52 on the guide rope wheel 4 malfunction or are damaged and need to be repaired, the operator can directly remove the small traction wheel 5 and bearing 52 for repair or replacement, without having to stop the entire equipment and remove the entire guide rope wheel 4 and the parts that fix the guide rope wheel 4. Several mounting shafts 51 are provided on the guide rope pulley 4. Bearings 52 are mounted on the mounting shafts 51, and small traction wheels 5 are fitted onto the bearings 52.
